Notes:
 Thetimedelaythatresultsfromthemeter’sautomaticsensingcircuit(1to2seconds)may
causeGFCIcircuitstoresetandbreakerstotrip.
 ItisnotrecommendedtousecalibrationequipmenttotesttheMA260.Calibratorscanbe
damagedifusedtotesttheMA260.

Accuracyisgivenas±(%ofreading+leastsignificantdigit)at23C±5Cwithrelativehumidity
lowerthan80%.Accuracyisspecifiedforaperiodofoneyearaftercalibration.
 ACVandACAspecificationsareforACCoupled,TrueRMS.Fornon‐sinusoidalwaveforms,
additionalaccuracyCrestFactor(C.F.)considerationsexistasdetailedbelow:
Add3.0%forC.F.1.0~2.0

Add7.0%forC.F.2.5~3.0
 Overloadprotection:AC1000Vrms,DC1000Vforvoltage,resistance,continuity,anddiode
functions.
 MaximumOpenVoltageforResistance/Continuitymeasurements:1.6V
 Continuitybeeper:Beepersoundswhenresistance
is<25ohmsandisoffwhentheresistance
is>400ohms.Notethatbetween25and400ohmsthebeepermaysound.
